Definitions

  • This invention relates to a method for manufacturing a floor covering.
  • the invention relates to a method for manufacturing a floor covering comprising at least a substrate layer, a decor layer and a translucent or transparent wear layer.
  • the invention is particularly interesting for being applied with floor coverings wherein at least said substrate layer and said transparent wear layer comprise thermoplastic synthetic material.
  • the thermoplastic material relates to so-called soft PVC (PolyVinyl Chloride), or PVC comprising a percentage of plasticizers, for example, of 5 to 20 percent by weight or even to 35 percent by weight or more.
  • the decor layer relates to a print, the decor of which may form a representation of a wood or stone pattern or any other pattern, such as a fancy pattern.
  • a relief or structure may be provided, such as a wood or stone structure, respectively.
  • thermoplastic nature of the transparent wear layer of such panels leads to problems when providing them with a structure, and without particular measures the sharpness obtainable up to now and the gloss degrees of the structure leave much to be desired.
  • the lack of difference in gloss degree results in an artificially-looking appearance of the floor covering.
  • US 2003/138617 describes a method wherein a chemical technique is applied for providing a wall-to-wall floor covering with a structure.
  • a selective foaming of thermoplastic material results in a relief at the surface of the floor covering.
  • This technique may be combined with mechanical impressions realized by means of a structured roller. Relief realized by means of a chemical technique is uncontrolled and lacks sharpness; moreover, the technique does not offer a solution for realizing structured parts with mutually differing gloss.
  • US2003/108718 A1 shows a method according to the preamble of claim 1.
  • the present invention relates to floor coverings of an alternative construction, such that new possibilities are created for the visual aspects of the surface, such as for the relief, and/or for the physical properties of the floor covering or panels.
  • the invention allows obtaining separate properties in the deeper-situated relief parts or recesses, where the first lacquer layer is present, and portions on the actual surface of the floor panel, where the second lacquer layer is present.
  • said first lacquer layer extends continuously over substantially the entire floor surface and/or said second lacquer layer extends over the portions of the floor surface which are located between said recesses. It is clear that according to this preferred embodiment, both lacquer layers can be situated on top of each other over the major part of the floor surface, and that the first lacquer layer can come to the surface at the location of the recesses only.
  • the floor covering obtained in the method of the invention shows a difference in gloss degree between the deeper-situated relief parts and the actual surface of the floor covering.
  • such difference in gloss degree then is obtained in that the first and second lacquer layer are realized with a difference in gloss degree.
  • the difference in gloss degree relates at least to a difference of 6 or still better 10 points as measured according to DIN 67530.
  • the difference is such that the one lacquer layer is perceived as matte, whereas the other is perceived as glossy.
  • the actual surface can be made wear-resistant or scratchproof by a skillful choice of the material of the second lacquer layer or its additives, whereas the deeper-situated relief parts are less wear-resistant or scratchproof, for example, in that the same additives are not or less available in the first lacquer layer.
  • An example of additives which can provide a certain scratchproofness are aluminum oxide particles.
  • the invention is of particular interest when it relates to supple floor coverings, preferably based on polyvinyl chloride. It is in such floor coverings that the artificial appearance can be minimized by means of the interaction of the lacquer layers.
  • the transparent wear layer substantially consists of a thermoplastic layer on which at least the aforementioned two lacquer layers are provided.
  • said thermoplastic layer comprises soft polyvinyl chloride.
  • the structured thermoplastic layer sometimes may show undesired gloss degrees, which then are neutralized in an effective manner by the lacquer layers of the invention.
  • the floor covering obtained in the method of the invention can be realized as a wall-to-wall covering or as a plurality of supple floor panels which have to be installed next to each other, for example, by adhering them to the underlying surface, or by installing them in a floating manner.

This may relate, for example, to locking tongue and groove connections, such as described in WO 97/47834 or EP 1 938 963 .
  • the floor covering obtained in the method of the invention relates to a floor covering which imitates a wooden floor.
  • said relief preferably relates to an imitation of wood pores.
  • a relief can be obtained in which the deeper-situated pores are made glossy, whereas the actual surface is made matte.
  • the gloss difference preferably is 6 points or more as measured according to DIN 67530.
  • each floor panel preferably relates to the imitation of a single wooden one-piece plank.
  • the overall thickness of the transparent wear layer preferably is at least 0.15 or 0.2 millimeters, whereas the thickness of the first lacquer layer as well as of the second lacquer layer is 0.05 millimeters or less, or still better 0.025 millimeters or less.
  • the invention relates to a method for manufacturing a floor covering according to claim 1.
  • the separate hardening techniques relate to radiation techniques by means of different wavelengths, such that each time, in a targeted manner, only substantially one of both lacquer layers is hardened. It is evident that to this aim the lacquer layers may be provided with different photo-initiators, which become active at the respective wavelength.
  • one of said two lacquer layers is hardened by means of UV radiation, whereas the other of said two lacquer layers is hardened by means of Excimer radiation.
  • the lacquer layer which is hardened by means of excimer radiation then can be made, for example, matte, whereas the other lacquer layer is made glossy. Obtaining a matte surface by means of an excimer-hardened lacquer layer is known as such from the document EP 2 154 184 A1 already mentioned above.
  • the second lacquer layer preferably is provided on the semi-finished product when the latter is already provided with the relevant relief and when the first lacquer layer is already situated on the semi-finished product.
  • the first lacquer layer may already be hardened or not hardened by means of the relevant technique.
  • said transparent wear layer shows a relief, preferably corresponding to a printed decor, such that a so-called structure, and possibly gloss degree, in register with the printed decor is obtained.

  • the printed decor may be provided on said substrate layer by forming this decor, by means of any printing technique, directly on the substrate layer concerned.
  • such decor is printed by means of UV-based inks.
  • said decor is provided on said wear layer, more particularly on the side thereof which is intended for being directed towards the substrate layer.
  • this relates to a so-called "reverse" print, wherein the usual color sequence of the inks is reversed.
  • such decor preferably is printed by means of UV-based inks.
  • a hard PVC film as a decor layer namely a PVC film without plasticizers, or of a PVC film having a percentage of plasticizers which is lower than 5 percent by weight, is particularly advantageous for obtaining a good registering between the printed decor and the structure of the wear layer. Due to the low percentage of plasticizer, such PVC films are less subject to dimensional alteration.
  • said thermoplastic material relates to polyvinyl chloride, and still better soft polyvinyl chloride, which contains, for example, a percentage of plasticizers of 5 to 20 percent by weight or even up to 35 percent by weight or more.
  • DINP or DOP can be chosen as the plasticizer.

So, for example, it is possible to achieve an IP value (Initial wear point) of 2000 or more in the Taber tests, as described in EN 13329, Annex E.
  • IP value Initial wear point
  • the restricted thickness of the wear layer namely between 0.2 and 0.4 millimeters, results in a better definition of the obtained structures, as in such case the springing back of the wear layer is restricted, too.
